Abstract

A fast digital sampler (waveform digitiser) has been used to measure the rise times and amplitudes of pulses from hydrogen - filled spherical proportional counters (type SP2). The rise time information allowed neutron events to be distinguished from gamma events, so that neutron data could be measured at energies below those possible with amplitude measurements alone. The associated electronics were considerably simpler than a conventional 2-parameter system. Some of the rise time distributions show interesting features that would be missed by systems that analyse only the pulse height.
